Behaviour of matter - Expansion

Behaviour of Matter-Expansion
When particle are heated, they begin to move around more and the space between the particles increases, causing the substance. Notice that the particles are vibrating more. Because of this, they are bumping into each other and the distance between the particles increases. This means the solid will expand.

Describe the effects of heat on:

1. The movement particles of solid, liquid, and gasses, the particles of a gas move quickly and are able to spread apart from one another. The particles of a liquid are able to move past each other.The particles of a solid are not able to move out of their positions relative to one another, but do have small vibrational movements.
2. The size of the particles In Materials science and Colloidal chemistry, the term colloidal particle is about a small amount of matter having size typical for colloids and with a clear phase boundary. The dispersed-phase particles have a diameter between approximately 1 and 1000 nanometers.
3. The space between the particles The empty space between the atomic cloud of an atom and its nucleus is just that: empty space, or vacuum. That's the simple answer, but there are a few subtleties Sub-atomic particles such as electrons, protons and neutrons need to be treated as quantum objects.
4. The size of the substance distribution of active ingredients and excipients is an important physical characteristic of the materials used to create pharmaceutical products. The size, distribution and shape of the particles can affect bulk properties, product performance, processability, stability and appearance of the end product.

Behaviour of Matter - Contraction

Solids, liquids and gasses all expand when they are heated. Similarly, When substance are cooled they contract as the particles move closer together 

The Imploding can

Aim: To observe contraction in gases 

Equipment: Aluminium can, scissor tongs, Bunsen burner, heatproof mat, tripod, gauze mat, an open container of water.

Method: 

1. Set up a Bunsen burner underneath a tripod and gauze mat.
2. Pour approximately 50-60 mL of water into your can. It should be no more than 1/4 full.
3. Heat the can of water until steam is seen is escaping from the top.
   Carefully grip the can with the scissor tongs. Ensure you have a firm hold of the can before lifting off the gauze mat.
4. Quickly, but very carefully, invert the can as you plunge it into a container of water.
